HR BIL WPD NMI-M10 Pattern Approved Turbine Water Meters - Table E Flanged

A highly accurate Woltman Parallel Turbine Water Meter pattern approved and tested in Australia for use in non-urban applications.

The BIL WPD Water Meter is a Woltman parallel turbine meter used for accurately measuring a wide range of flow rates with a mainly constant flow rate profile.

The housing and internals are hydrodynamically optimised for highly accurate and stable measurement. Combining the use of high-quality composite plastics with a specially enhanced impeller bearing ensures consistent performance over the operational life of the water meter.

The pattern approved BIL WPD Water Meter is designed and tested over a wide measuring range and provides accurate measuring results over a long period making it suitable for all non-urban applications where NMI-M10 Pattern Approved meters are required between 50mm and 300mm diameter.

Key Characteristics

• Wide measuring range, small pressure loss
• Low starting flow and high overload security
• Pulse output with integrated reed switch
• Long-term accuracy and stability
• Swirl-reducing inlet design
• Replaceable measuring internals
• Water-proof (IP68), hermetically sealed, glass/copper register
• Solid cast iron construction with durable epoxy coating for exposure to field applications
• 50mm – 300mm (2” – 12”)
• Table E flanged inlet/outlet

Applications

• For the measuring of high flow rates
• For horizontal or vertical installation
• For cold water up to 50°C
• For applications where NMI-M10 Pattern Approved water meters are required

Installation

For monitored irrigation installation requirements, refer to you relevant Government authority for standards, certifications and approvals.

For other general applications:

• The water meter may be installed in either a horizontal or vertical position. For vertical positions the flow should always be upwards.
• The meter must be installed to ensure the pipe and water meter are full of water whilst operating.
• Prior to installation, the pipeline should be thoroughly flushed to remove any debris or contaminants.
• Straight pipe sections before and after the meter are:

– For DN50 water meters: 5x diameter of straight pipe before the meter and 2x diameter of straight pipe after the meter;

– For DN80 to DN300 water meters: 10x diameter of straight pipe before the meter and 5x diameter of straight pipe after the meter; and

– Where diameter refers to the nominal diameter of the water meter.
